How does sauna improve longevity?

Sauna exposure has multiple benefits that contribute to improved longevity, primarily through its impacts on cardiovascular health and overall mortality reduction.

1. Cardiovascular Health: Regular sauna use (2-3 times per week) has been linked to a significant reduction in the risk of dying from cardiovascular events. This effect is even stronger with more frequent visits (4-7 times per week). This reduction in cardiovascular-related mortality is believed to be due to the sauna's influence on heart rate and blood pressure, which mimic the effects of moderate physical exercise 1 2.

2. All-Cause Mortality: Beyond just cardiovascular health, regular sauna use contributes to reduced all-cause mortality, which includes deaths from various causes other than cardiovascular diseases. This suggests a general benefit to overall health and longevity 1.

3. Molecular and Genetic Benefits: Sauna use upregulates the FOXO3 pathway, which is linked to DNA repair and the clearing of senescent cells. These processes are crucial for maintaining cellular health and preventing the onset of diseases associated with aging 3.

4. Mimicking Physical Exercise: Sauna sessions can replicate some of the physiological responses elicited by moderate physical exercise, such as elevated heart rate and lowered blood pressure post-sauna, which are beneficial for individuals unable to engage in traditional forms of exercise 4.

These findings underscore the potential of regular sauna use as a viable means to enhance longevity by promoting cardiovascular health, reducing mortality rates, and supporting crucial cellular functions.
